Cucumber seedlings were subjected to salt, drought and cold treatments for 0, 0.5,1, 3, 6 12 and 24 h.

Note:

nc, no significant change in gene expression; +, moderate induction of gene expression; ++, strong induction of gene expression; -, reduction of gene expression.

Student's t-test was used to obtain the statistical significance of the difference between treated samples and untreated samples (0 h treatment under abiotic stress). If P-values < 0.01, we considered the WRKY gene as an induced gene.
